Mastercard Fraud Prevention

If you knew of a system that prevents fraud with your credit cards, would you use it? In Caribe Federal we want you to feel confident that your finances are in good hands. That’s why we offer our automated transaction monitoring. With this system we can detect any unusual transaction that may be high-risk in your accounts, and we can block your credit card account in a preventive manner.

These are some of the transactions that fall under the high-risk line:

Transactions outside Puerto Rico, if you are living in Puerto Rico

Unusual transactions made through telephone or internet

Transactions with high-risk online stores

First transaction generated in a previously inactive account

Excessive transactions in a short period of time

Transactions above $1,500

Transactions in China

Before making a preventive block to your credit card, an officer will try to contact the credit card owner to verify that the transaction was made by him/herself.

For this reason, we urge all our members to:
